水电站励磁系统基于ICPT技术的优化改造

滑环系统是水轮发电机组励磁系统中动静接触、能量交换的重要环节。根据国内水电厂的调研情况,滑环系统碳刷刷辫过热熔断、接触面打火等问题普遍存在,严重危及发电机组的稳定运行。对此,提出一种基于ICPT技术的新型水电站励磁系统,并给出该新型系统的设计及应用建议,旨在为水电站励磁系统的研究提供一种新思路。

Optimizing Modification of Hydrogenerator Excitation System Based on ICPT Technology

The slip ring system plays a very important role in linking rotating and stationary, exchanging energy in the hydrogenerator excitation system. According to the investigation, the problems, such as carbon brush braid overheating and fusing, electric spark, are very common, which seriously threaten the safety and stability of hydrogenerator. To solve the above problem, this paper presents a ICPT based hydrogenerator excitation system, and offers some suggestions on design and application, which provides a new idea for the study of hydrogenerator excitation system.
